The first Silversides (SS-236) was laid down on 4 November 1940 by the Mare Island Navy Yard, Vallejo Calif., launched on 26 August 1941, sponsored by Mrs. Elizabeth H. Hogan; and commissioned on 15 December 1941, Lt. Comdr. C. C. Burlingame in command.

After shakedown off the California coast, Silversides set course for Hawaii, arriving at Pearl Harbor on 4 April 1942. Departing Pearl Harbor on the 30th, Silversides headed for the Japanese home islands, in the area of Kii Suido, for the first of her many successful war patrols. On 10 May, the submarine sank a Japanese trawler with her 3-inch gun. During this action, an enemy machinegun bullet killed one of her deck gunners. In retaliation, the submarine's gunners riddled the enemy until he spouted flames and sank On 13 May Silversid es torpedoed an enemy submarine; but, although explosions were heard, a definite sinking could not be confirmed.

On 17 May, Silversides torpedoed and sank a 4,000ton cargo ship and damaged a second in one of the more interesting engagements of the war. While maneuvering through an enemy fishing fleet and approaching the cargo ships, the submarine's periscope became entangled in a fishnet marked by Japanese flags held aloft on bamboo poles. Silversid es bored in on the ill-fated enemy ships, fishnet and all, and fired three torpedoes at the first ship, with two hits that tore her stern open. While that ship was sinking, the second cargo ship was also hit, but its fate could not be determined. Patrol boats were closing in as the submarine, probably the only American submarine to make an attack while flying the Japanese flag, quickly left the vicinity. After damaging a freighter and tanker in the same area, Silversides terminated her first war patrol at Pearl Harbor on 21 June.

Silversides' second war patrol was also conducted in the area of Kii Suido, from 15 July to 8 September. On 28 July, she sank a 4,000-ton transport, followed by the sinking of the passenger-cargo ship Nikkei Maru on 8 August. She scored damaging hits on a large tanker on the night of the 14th and, on the 31st, sank two enemy trawlers before returning to Pearl Harbor.

Although there were no confirmed sinkings during Silversides' third war patrol, conducted in the Caroline Islands, the submarine did do severe damage to a large cargo ship and gained two observed torpedo hits on a Japanese destroyer or light minelayer for undetermined damage. She terminated her third patrol at Brisbane, Australia, on 25 November.

Silversides departed Brisbane on 17 December and set course for New Ireland for her fourth war patrol. While far out at sea on the night of Christmas Eve, the submarine's pharmacist's mate performed a successful emergency appendectomy on one of the crewmen. With the operation over at 0400 on the 25th, the submarine surfaced only to be immediately forced down by a Japanese destroyer and compelled to endure a severe depth charge attack. Thinking herself safe, Silversides surfaced only to find the destroyer still there. In addition, a Japanese airplane had arrived on the scene, and proceeded to drop three bombs on the submarine, severely damaging her bow planes and causing them to look on full dive. Silversides managed to level off just short of crush depth and eventually evaded the enemy ship before surfacing to recharge her batteries and effect emergency repairs.

While off Truk on 18 January 1943, Silversides torpedoed and sank tanker Toei Maru. Two days later the submarine had one of her most productive days of the war. After paralleling a convoy throughout the daylight hours, she moved on ahead at sundown to lay in wait. As the bargets moved into range, she fired her torpedoes at overlapping targets and sank three enemy ships-the cargo ships Surabaya Maru, Somedono Maru, and Meiu Maru. The attack had scarcely abated when it was discovered that an armed torpedo was stuck in a forward torpedo tube. Since it was impossible to disarm the torpedo, the commanding Officer decided to attempt to refire it, an extremely dangerous maneuver. The submarine moved in reverse at top speed and fired. The borpedo shot safely from the tube, disappearing as it moved toward the horizon.

When a serious oil leak was discovered later that night, the submarine left the patrol area two days ahead of schedule and returned to Pearl Harbor on 31 January.

Silversides' fifth war patrol commenced on 17 May and was conducted in the Solomon Islands area. Her primary mission was to lay a minefield in Steffan Strait, between New Hanover and New Ireland, but she did not neglect enemy shipping. On the night of 10 and 11 June, she sank the 5,256-ton cargo ship Hide Maru; but, for her efforts, was forced to endure a severe, though fruitless, depth charging. She returned to Brisbane for refit on 16 July.

For her sixth war patrol (21 July to 4 September)

Silversid es patrolled between the Solomon and Caroline Islands. Since she was plagued with malfunctioning torpedoes and a scarcity of targets, she returned to Brisbane empty-handed.

Silversides set sail on 5 October for her seventh war patrol in which she sank four enemy ships in waters ranging from the Solomons to the coast of New Guinea. On the 18th, she torpedoed and sank the cargo ship Tairin Maru, and, on the 24th, made a series of daring attacks to send the cargo ships Tennan Maru and Kazan Maru and the passenger-cargo ship Josore Maru beneath the waves. She returned to Pearl Harbor for refit on 8 November.

Silversides patrolled off the Palau Islands for her eighth war patrol where, on 29 December, she brought havoc to an enemy convoy of cargo ships, sinking Tenposan Maru, Shichisei Maru, and Ryuto Maru. She terminated her sixth patrol at Pearl Harbor on 15 January 1944.

For her ninth war patrol, Silversides departed Pearl Harbor on 15 February and set course for waters west of the Marianas. On 16 March, she sank the cargo ship Kofueu Maru; but, since the remainder of the patrol was void of worthwhile targets, the submarine returned to Fremantle on 8 April.

While on her tenth war patrol, off the Marianas Islands, Silversides destroyed six enemy vessels for a botal of over 14,000 tons. On 10 May, she torpedoed and sank the cargo ship Okinawa Maru, followed up with the passenger-cargo ship Mikage Maru; and then sent the converted gunboat Cohan Maru No. 2 beneath the waves. Ten days later, she added to her score when she sank another converted gunboat, the 998-ton Shosei Maru. On 29 May, the submarine torpedoed and sank the cargo ships Shaken Maru and Horaizan Maru; and then headed for Pearl Harbor, arriving on 11 June. Two days later, she got underway for Mare Island Navy Yard for overhaul, returning to Pearl Harbor on 12 September.

Silversides set sail on 24 September for her eleventh war patrol, conducted off Kyushu, Japan. Although this patrol was unproductive, she aided in the rescue of a stricken sister submarine. Salmon (SS-182) had been badly damaged in a severe depth charging and was forced to surface and try to escape while fighting enemy escorts in a gun battle, a task for which a submarine is badly outmatched. The gunfire flashes brought Silversides to the scene. She deliberately drew the attention of some of the escorts, then quickly dove to escape the gunfire. Soon submarines Trigger (SS-237) and Sterlet (SS-392) joined in helping Silversides to guard Salmon, and in escorting the stricken submarine back to Saipan, arriving on 3 November. Silversides terminated her eleventh patrol at Midway on 23 November.

Silversides' twelfth war patrol commenced on 22 De
cember and was spent in the East China Sea. Despite
aggressive search, she found few worthwhile targets.
However, when an opportunity did come her way, Siversides took full advantage. On 25 January 1945, she slammed home torpedoes to sink the 4,556-ton cargo ship
Malay Maru. She returned to Midway on 12 February.During her thirteenth war patrol, Silversides was a member of a coordinated attack group with Hackleback
(SS-295) and Threadfin (SS—410), patrolling off Kyushu. Although she again found few worthwhile targets, the submarine did manage to damage a large freighter and to sink a trawler before returning to Pearl Harbor on 29 April.

Silversides' fourteenth and final war patrol began with departure from Pearl Harbor on 30 May. This patrol was spent on lifeguard station in support of air strikes on Honshu, Japan. On 22 July, she rescued a downed fighter pilot from the aircraft carrier Independence ( CV-22), and two days later recovered a downed United States Army airman She ended this patrol at Apra Harbor, Guam, on 30 July. The submarine was undergoing refit there when the hostilities with Japan ended on 15 August.

Silversides transited the Panama Canal on 15 September, arriving at New York City on the 21st. After shifting to New London, Conn., she was decommissioned on 17 April 1946 and placed in reserve until 15 October 1947, when she was placed in service as a training ship for naval reservists at Chicago, III. She remained there for the rest of her service. On 6 November 1962, she was reclassified as an auxiliary submarine (AGSS)

and, on 30 June 1969, her name was struck from the Navy list. The South Chicago Chamber of Commerce has applied to the Navy Department for custody of Silversides to preserve her as a memorial.

Silversides (SS-236) received twelve battle stars for World War II service.
